RESPONSE OF YOUNG CLEMENTINE CITRUS TREES TO DRIP IRRIGATION

Juan R. Castel
Young Citrus trees (Clementina de Nules/Citrange Carrizo) were subjected to 8 drip-irrigation treatments during two consecutive seasons (1988–90). Treatments consisted in the application of 30, 40, 50, 60, 70, 80, 130 and 200% of evapotranspiration measured by water balance in 4 drainage lysimeters planted with similar trees. Irrigation was applied by 2 emitters/tree with the same frequency for all treatments.

Water use measured in the lysimeters was 35 and 54 mm/year for the first and second seasons, respectively. For the period 1985–89,Kc was well correlated with ground cover (r2=0.93) and leaf area index (r2=0.85).

Irrigation amount affected significantly (p<0.05) tree growth (trunk perimeter, percentage of ground cover and canopy volume). However, no clear functional relationship between applied water and relative growth was observed.
